Given below are two statements, one is labelled as Assertion (A) and other as Reason (R) :
Assertion (A) : Ambient air quality of Delhi is deteriorating day by day.
Reason (R) : Stubble burning in Panjab and Haryana affects air quality in Delhi.
Select the correct answer from the codes given below :
Codes :
MH SET - 2020, SET Exam - 2020,
Answer: B
The key's answer is that both (A) and (R) are correct, but (R) is not the correct explanation of (A).
Delhi's ambient air quality is poor and has worsened, and smoke from stubble burning in Punjab and Haryana does reach Delhi and adds to its pollution. Both statements are therefore true.
But stubble burning is seasonal, concentrated in October and November, while the assertion speaks of air quality deteriorating day by day. The year-round causes lie mainly within the region: vehicle exhaust, road and construction dust, industry, power plants and waste burning, made worse by winter weather. So stubble burning contributes to, but does not explain, the assertion.
